What Raw Garlic Does for Your Body
Research on cardiovascular health consistently highlights garlic as a powerful natural aid. It supports heart health in several ways:
1. A major benefit for heart health
Lowering blood pressure:
A clinical trial published by the National Institutes of Health found that participants with hypertension who took aged garlic supplements for three months experienced a significant reduction in blood pressure.
The effect was comparable to some prescription medications. According to Dr. Sudha Raj, a nutrition professor at Syracuse University’s Falk College, garlic helps the body produce nitric oxide, which relaxes and widens blood vessels, improving blood flow. It also reduces ACE (angiotensin-converting enzyme) activity—similar to how some blood pressure medications work.
Keeping arteries clear:
Dr. Wendy Bazilian, a public health expert and nutritionist, notes in research published in the American Journal of Clinical Nutrition that compounds in the allium family (garlic, onions, leeks, and shallots) reduce platelet “stickiness.” When platelets are less likely to clump together, the risk of blood clots decreases. This helps prevent atherosclerosis, the buildup of plaque in arteries that can lead to heart attacks and strokes.
Lowering cholesterol:
Studies also suggest garlic may reduce LDL (“bad”) cholesterol by 10–15%. While garlic alone is not a cure, when combined with a balanced diet, regular exercise, and stress management, it can support overall cardiovascular health.
2. Supporting the immune system
Garlic has been used medicinally for thousands of years, long before its mechanisms were understood. It contains vitamin C, vitamin B6, manganese, and a high level of antioxidants.
Antioxidants help combat oxidative stress, which is linked to chronic diseases such as heart disease and neurodegenerative conditions like Alzheimer’s and dementia.
Regarding the common cold, data compiled by the National Cancer Institute suggests that while raw garlic may not shorten a cold once you are sick, regular consumption may help reduce the likelihood of catching one in the first place.
3. Long-term cellular protection
The benefits of allium vegetables extend beyond seasonal illness. Large-scale nutritional studies from the National Cancer Institute suggest that higher intake of allium vegetables in women is associated with a lower risk of osteoarthritis.
Research is also ongoing into garlic’s potential anti-cancer properties, including its possible role in reducing the risk of prostate cancer, lung cancer, brain tumors, and even alcohol-related liver disease.
